United Kingdom - Passport & Nationality - British Citizenship by Double Descent (Pre 83 Birth Colony)
This is an exceptional situation caused by an anomaly in the drafting of British Nationality Law.
a) Applicant born anywhere between 01.01.1949 and 01.01.1983;
b) Parent born in a British Colony which retained its Colony status after 01.01.1949; AND
c) Applicant has the Right of Abode via a UK-born parent, paternal grandfather or maternal grandparent.
A successful application will have to rely on:
1. both the applicant and the relevant parent not suffering from the Automatic Loss provisions that occured upon Independence of the Colony; AND
2.legitimate birth in wedlock (however, if this is not the case, a successful may succeed depending on the circumstances).
The list of British Colonies excludes those territories given wide powers of self-governance and control over Foreign Policy. So this excludes South Africa, Australia, New Zealand, Canada, India, Ceylon and Southern Rhodesia.
